My'inventionhas relation to a pressand/or process for the manufacture of teapot spouts" or like articles of pottery, and has for its object to provide for the particularly expeditiou's, uniform and generally efficient manusolid body within the engaging upper and lowerdies: and render same of the desired hollow tubular formation.

Conveniently the lateral coring dies may haveopposediarcuate movements to give the desired sinuous conduit within the'solid body,

and maybe actuated simultaneously by a' common hand lever. One coring die maybe inthe form of an arcuate rod, "and the other of bulbous nose formation, to constitute'the flared inlet, the adjacent part of whichis afterwards engaged with the body of the pot and each or eithercoring die may have a bearing face adapted to close the adjacent open extremity of the cavity constitutedby theupper "and-lower dies, for giving a ter minal finish tothe spout at either or both the pouring andattachment extremities. The upper die may be brought into engagement with the lower die by apedal mechanism,

whereas, as previously intimated, the lateral coring dies may be'operated simultaneously by'an iudependentsingle hand lever. If desired, one lateral coring die may be in the nature of a straight rod so that the outlet portion of the conduit in the spout is of straight formation.

The coring dies are preferably adapted to engage one within the other at their extrem- 455 itiesto ensure extrusion of the internal mass, and'such extrusion may be facilitated by providing a conduit in one of the lateral die elements through which the superfluous body being moulded may passor flow.

In order that this invention may be clearly understood and readily carried into practice,

reference may be "had to the appended eX- planatory sheet of'drawings upon'which: Figure -1 is a sectional plan view illustrating a pressingmechanism for the manufacture of a teapot or like spout constructed according tothe present; invention. I Figure 2 is afront elevational view of the press shown in Figurel. g Y F igure3 is a sectional plan view corre-; sponding tothe Figure 1, illustrating the press infthe open condition. i 1 Figure t is a sectio' a1 plan View of'a pressing mechanism hereinafter referred; to, slightly modified. f i I In a convenient embodiment'ofthe present invention, theflower die a is mounted upon atable b supported'bya suitable substruc ture.- The upper'clie (Figure 2) is ca'rried' by a cross bar-'ol which is slidable upon two '.v

uprights e carried'by the table 6, the said cross bars being'ope'rated through the me dium ofrodsj which pass through apertures in the table, to: a suitably weighted foot pedal mechanism notshown); Upper and 7 lower dies cand a;respectively are in intagl'i'oor relief and of substantially the same configuration, each beingadapted to form a half'of the-spout, that isftosay, a half con sideredwhen the spout is split longitudinally along itscentre plane. Pivoted'to-the table at g is a hand-lever 9 (Fig. ,3) and a part 9 of said le'ver is extended beyond its pivot and is 'con'nected by means of a connecting linkto a rocking shank ipivoted at i to the stationary: table '5." is a further rocking member pivoted at 9' to the stationary table I) and linkedto the lever g by means of the rod in The rocking shank z" carries the bulbous like coring die Z and the rocking-memberxcarries' the curved rod 'like coring die which is adapted-to enter asmall cavity Z at the extreme end of the die Z. The diel is further provided'with' an extrusionroutle't- Z and an associate closure or hearing face Z and the die m is also provided with a clo sure-or-bearing face m the'purpose of these closure on-bearing faces beingto close or cooperate with" the extremities of the'mould 2 passlng along the conduit Z.

In a modification of the present invention, instead of using an arcuate rod-like coring die m I may employ a straight rod-like coring die a (Figure 4) adapted to have an axial sliding movement within a suitable guide 0, so .as to slide between the main dies at 0 for the purpose of this-invention. Such a die n may be connected to the hand lever extension 9 by means of a link p and rotary disc g.

In operation, a lump of plastic clay or like body is placed in the cavity in the lower stationary die 6, and the upper die 0 is caused to descend by the foot-pedal mechanism to virtually constitute a solid teapot spout or a portion thereof. By manipulating the hand lever g, the lateral coring dies Z m are simultaneously urged into the solid body until the rod-like die m is engaged with the extreme end of its complementary die Z.

Simultaneously or finally, the ends of the main dies a c are closed or completed by the bearing faces m m aforeinstanced, and the spout is completed, the superfluous. body The lateral coring dies Z on are retracted, and the upper die 0 elevated, when the spout '1" may be removed and, if desired, trimmed. The extreme ends of the spout are or may be defined by the bearing faces associated with the 0pposed coring dies in co-operation with corresponding faces associated with the upper and lower dies. Alternatively, stationary faces may be provided for defining the extreme ends of the spout, through which sta-' tionary faces the coring dies may be caused to protrude in the operation of the apparatus. The upper and lower main dies may have flutings, to give a desired enhanced ap .pearance to the lower bulbous part of the spout.

l/Vhat I claim as my invention and desire to secure by Letters Patent is: V

1. A press for the manufacture of teapot spouts or like articles of pottery, comprising upper and lower intaglio dies or moulds adapted to press a plastic clay or like body into a solid spout formation, and lateral coring dies adapted to be thrust into and out of engagement one with another, to core the solid body within the engaging upper and lower dies and render same of the desired hollow tubular formation.

2. The mode of manufacturing a teapot spout or like article of pottery, consisting in first pressing a plastic or like body causing it to assume the shape of a spout and then simultaneously piercing the same from each end while holding the plastic body in the pressed condition. 7

3. A press for the manufacture of teapot spouts or like articles of pottery, comprising dies or moulds in intaglio adapted to be brought together to constitute a hollow mould the extremities of which are open, and

two opposed coring dies one adjacent each open extremity of the mould and adapted to be shot into the said mould into engagement with one another.

4. A press for the manufacture of teapot spouts or like articles of pottery, as claimed in the last preceding claim, wherein faces are associated with the coring dies adapted to close the open extremities of the mould for shaping the extreme ends of the article and/or abut against the extremities of the said mould for stop limiting purposes. 5. A press for the manufacture of teapot spouts or like articlesof pottery, comprising upper and lower intaglio dies, adapted to form a complete mould, coring dies adapted to be introduced from the extremities of the complete mould and a passage or outlet adapted to permit of extrusion of the superfluous body during the moulding operation.

6. A press for the manufacture of teapot spouts or like articles of pottery, as claimed in claim 3, wherein one coring die is in the form of a bulbous nose and the complementary coring dieis in the form of a rod, the extreme end of which is adapted to be accommodated in a small cavity in the tip of the bulbous nose. 7

7. A press for the manufacture of teapot spouts or like articles of pottery, as claimed in claim 3, wherein each coring die is adapted to have an arcuate movement on a fixed pivot, and wherein the rod like die is of bent or curved formation.

8. A press for the manufacture of teapot spouts or like articles of pottery, as claimed in claim 3, wherein a conduit is provided through one of the coring dies, through which the superfluous body being moulded is adapted to flow.

9. A press for the manufacture of teapot spouts or like articles of pottery, comprising intaglio dies adapted to be brought into engagement, a foot pedal mechanism for operating said dies, coring dies. and an independent handle mechanism for synchronously operating said coring dies.

10. A press for the manufacture of teapot spouts'or like articles of pottery, as claimed in claim 3, wherein one of said coring dies is of straight rod-like shape and has an axially sliding mounting for the purpose set forth.

In witness whereof I have hereunto set my hand.
